rotundifolia, is a wellknown remedy for treating QItGI'lO-SClGlTOSlS.

making this decoction, however, the eflec tive substances, the proteolytic ferments, generally suffer, as they cannot stand such high temperatures.

The subject of the present invention is an extract of Drosera rotundifolia, in which the effective fermentsfare completely preserved and a process of making same.

According to the invention the extraction of finely ground Drosera is effected, instead of by boiling water, by an approximately 5% solution of silicate of sodium. For improving the taste a little sugar is added to the solution. The extraction must be carried out in'such a manner that the free silicic acid remains in solution.

ceeded. The concentration is continued as long as the silicic acid remains insolution, a solution being obtained containing aboutone milligram SiO per cubic centimeter. In I its therapeutic effect the new preparation far exceeds the effect of silicate of sodium and the effect of an extract of Drosera.

\Vhat I claim is:

1. A process for producing a preparation of Drosera comprising subjecting finely 4 ground Drosera to extraction with a solution of silicate of sodium, while avoiding the precipitation oft-he silicic acid, and thereupon inspissating the solution in a known manner in a vacuum to a state of concentration such that the silicic acid on'lyjust remains in solution.

2. As a new composition of matter, a concentrated extract of Drosera with asolution of sodium silicate, said extract containing about one milligram SiO per cubic centimeter. i I

In testimony whereof I'aflix my signature. I
